New developments in a case of a missing young woman. Heather Elvis vanished after arriving home from a date. Now a husband and wife are facing charges as authorities intensify the hunt. Reporter: Good morning to you, it's been 69 days since heather Elvis went missing. Investigators say it was survey lense videos and financial issues that led to a south Carolina's couple arrest. And one thing that the missing girl's father that may have helped lead to the suspects. This morning Sydney and tammy Moore are behind bars in connection with the disappearance of heather Elvis. I want to feel happy, but there's no joy. Elvis went missing in December. Car abandoned, no sign. And frustratingly slow progress until Friday where they raided the couple's home. Anything we release at this point could do a lot more harm than good. The break through coming from a discovery by Elvis' father. He looked up her cell phone records. There were a lot of calls to one particular number in the last hours before the phone stopped working. That number, the parents telling ABC news, belonged to 38-year-old Sydney mayorerer. He and Elvis may have had a romantic relationship. The couple appeared in court on Saturday, held on $20,000 bond, each facing from counts of indecent exposure. But investigators say much stronger charges soon. Either a missing person or a homicide. That's the focus. For the Elvis family, a small measure of relief in the ordeal. This is torture for everyone. If they would just talk and tell us what happened. I really believe they know where heather is. The couple could face up to 16 years in prison, both are due back in court on may 2nd. There is a $30,000 reward for information that could advance the case. That's amazing that it was the father who did so much of the investigative work. Thank you for that report.
